SPINNING RlNG AND FRAIVI E.

SPECIFICATION forming part of Letters Patent No. 232,818, dated October5, 1880.

Application filed August 6, 1879.

To all whom it may concern:

Be itknown that I, ELISHA HARRIS, ofProvideuce, in the State of RhodeIsland, have made certain new and useful Improvements in Spinning Ringsand Frames; and I do hereby declare that the following specificatioi'i,taken in connection with the drawings, making a part of the same, is afull, clear, and exact description thei\ .of.

Figure 1 is a view of a spinning ring and traveler with gear for drivingthe same. Fig. 2 is a section of same, showing the manner oflubricating. Fig. 3 is a side view of the ring with a part broken away,to show the con- 1 5 struction and adjustment of the different parts.Fig. 4 is a cross-section on the line ax of Fig. 2. Fig. 5 is a sideelevation of a spinningframe, showing the mechanism for driving thespindles and rings. Fig.6 is an end elevation of the same. Fig. 7 showsthe surface of the cam-pulley. Fig. 8 is an enlarged view of thespindles and rings, showing particularly the means by which the latterare rotated. Fig. 9 is a top view of the ring-rail, showing the gearedconnection for rotating the rings. Fig. 10 is a diagram, showing a topview of the bobbin and the angle or leverage of the yarn in passingthrough the traveler during the pro cess of winding the bobbin. Fig. 11shows a full bobbin of yarn. Fig. 12 is a sectional detail, to bereferred to.

The object of inyinvention is to spin a com tinuous thread, and lay thesame upon a bobbin or quill of small or large diameter in a compact,sound, and even condition, and to render the spinning-frame capable ofbeing stopped and started at any point of the wind without breaking thethread; and it consists in the improvements in the spinning-ring and inthe means of rotating the same at proper intervals, as hereinafterdescribed.

The yarn is laid upon the bobbin in conical form, commencing at thebottom thereof, and by a graduated movement passes up and down until thebobbin is wound full, as shown in Fig. 11.

The yarn passing from the front rolls through the traveler to the bobbinsustains the least amount of strain, while it has the greatest 5oleverage upon the traveler-that is to say,

while it is being wound upon the greatest diameter of the bobbin-theangles of leverage being shown in Fig. 10. The strain of the yarn isincreased as the wind moves upward from the large to the smallerdiameter of the bobbin, such increase resulting from the decrease of theleverage of the yarn upon the traveler. The yarn passing through thetraveler while being wound upon the smaller diameters of the bobbin alsoincreases the friction of the traveler in contact with the ring inproportion to the leverage of the yarn upon the traveler. The frictionof the traveler, produced in the manner described, brings a great andunusual strain upon that portion of the yarn which is 6 5 wound upon thesmaller diameters of the bobbin, which often results in breaking theyarn and always in straining and weakening it.

In stopping the ordinary spin ning-frame care must be taken to stop itat that point in the wind where the tension is slightest; otherwise thethreads are liable to break by the sudden starting of the machine.

To obviate the difficulties which I have described, and to counteractthe increase in the friction of the traveler upon the ring and of theyarn through the traveler, both of which tend to increase the tension ofthe yarn as the wind of the yarn upon the bobbin moves from the largerto the smaller diameter, is the ob- 8o ject of my invention.

I find by experiment that the difficulties described may be overcome byrotating the ring at proper'intervals at a varying rate of speed and inthe direction of the rotation of the 8 5 bobbin, the duration of suchrotation and the speed thereof being adjusted to the natural increase oftension upon the yarn attendant upon the upward movement of the wind.upon the bobbin. 9o

In my invention, A, Fig. 1, is the ring, and B the traveler. The ring A,instead of being set in the rail, is placed upon the hollow axis 0,which is stationary in the ring-rail. Upon the axis 0, and attached tothe ring A, is a 5 gear, D. The ring A and the gear D are bothconstructed and arranged to rotate upon the axis 0, as shown in Figs. 1,2, 3, and 12, the upper surface of the gear D being provided with twopins, 15, diametrically opposite, which roe enter corresponding holes(see Fig. 12) in the under side of the ring A, to insure theirsimultaneous revolution. The rings A, for the purpose of receivingmotion, may be grouped into sets of two or more, the rings of each setbeing connected by intermediate gears A, Fig. 8, and having adriving-gear, as hereinafter described.

In my invention I make use of one drivinggear, B, for sixteen rings, asshown in Fig. 5. The driving-gear is connected by feather-keying thegear B to the grooved spindle G, as shown in Figs. 5, 8, and 9, thelower end of which is a fixed whirl, Il.

The spindles Gr, to which the several drivinggears are attached, areconnected by suitable bands to a shaft, I, Fig.5, which is connected bya belt, J, to a shaft, K. The shaft K is provided with a conical drum,L, which is connected by a belt, M, with a conical drum, N, upon thedriving-cylinder shaft 0, which drives the spindles (t a a, &c., bymeans of suitable bands passing around the fixed whirls I) b I).

P is a loose pulley upon the shaft K, at the base of the conical drum L.

Q is a cam-pulley upon a shaft, B, which shifts the belt M through thelever T, rack a, and guide 12. The shaftR has a uniform movement, and isrotated by the bevel-gear W through the shaft X, gear and worm Y, andshaft Z, which is rotated by means of any suitable mechanism from themain driving-pulley c or front rolls.

The rods S S, for raising and lowering the rail, are constructed andoperated in the same manner as in the machines now in use, and do not,therefore, require particular description.

Having described the several parts of the machine, I will now proceed todescribe its operation.

The yarn moves upward in its wind, the same as in the machines now inuse. until it reaches that point where the strain becomes injurious.This point is determined by the judgment of the operator, and themechanism adjusted in accordance therewith, so that upon the attainmentof that point the cam-pulley Q, operates the lever T, which is providedwith a curved transverse toothed bar operating in the rack 21, andthrough the guide 1: slides the beltlVI from the loose pulley P. As soonas the belt M leaves the loose pulley P it passes onto the conical drumsL N, and the rings A begin to rotate at a slow rate of speed through themechanism already specified and shown in Figs. 5,8, and 9. As the windcontinues to move upward from the point where the rings begin to rotatethe strain naturally increases, and is met by thecorrespondingincreasein the speed of the rings consequent upon thecontinued outward movement of the belt M upon the conical drums LN untilthe highest point is reached. As

the wind now descends the speed of the rings gradually decreases as thebelt M moves inward, operated, as before, by the. cam-pulley Q and themechanism already described, until the belt is again upon the loosepulley and the rings are still, where it remains until the point in theupward movement is again reached, when the same operation is repeated.

The ring is at all times rotated in the same direction as the bobbin,but at a much less rate of speed, and it will be evident that thevarying strain upon the yarn will be met by the varying speed of thering.

In Fig. 10 c isthe outside diameter of the bobbin,fthe diameter at thepoint in the wind where the tension becomes too great, and g is thequill or spindle.

h t'j indicate the respective positions of the traveler through whichthe yarn passes while it is being wound upon the diameters of g, and thelines it t m, together with the lines a op, running through the centerof the spindle, show the degrees of the different angles correspondingto the different diameters of the bobbin.

The mechanism for rotating the rings at the proper intervals and at theproper speed is susceptible of various changes, as the taste orpreferences of different mechanics may dictate.

To provide for the lubrication of the axis 0, upon which the ring Arotates, I construct the ring proper in two parts with a band, E.Underneath the band E is an annular groove, F, in the ring, which isfilled with fibrous material to take up the oil which is receivedthrough the channels 8, leading from the outside of the ring, anddistributed and discharged upon the axis through holes t, made for thatpurpose.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The ring A, provided with the annular groove F, in combination withthe band E, traveler B, gear D, and hollow axis 0, the whole constructedin the manner substantially as described, for the purpose of enablingthe rin to be rotated on its axis, as specified.

2. The ring A, in combination with the hollow axis 0, gear D, travelerB, and mechanism for rotating the gear 1), consisting of the gear B,spindle G, shaft I, belt J, shaft K, loose pulley P, cone-drum L, beltM, cone-drum N, shaft 0, guide V, rack U, lever T, cam-pulley Q, shaftR, gear W, shaft X, worm Y, and shaft Z, constructed and operatingtogether, for the purpose of giving the ring an automatic intermittentrotary motion and accelerating and retarding the speed of the sameduring the continuance of such rotary motion, as and for the purposesspecified.
